5G wireless systems: principles, IoT connectivity, and slicing of radio resources
(2019-06-07)In the conference, the landscape of future wireless connectivity is first described. Later, a glimpse into the new radio and standardization is given. New modes in 5G are treated in deep, emphasizing those related to ... -
El 9/11 y la teoría del choque de civilizaciones entre Occidente y el Mundo Árabe: la visión intermedia de Naguib Mahfouz
(Servicio de Publicaciones y Divulgación Científica, 2015)Los ataques del 11 de septiembre de 2001 en Estados Unidos, más conocidos como 9/11, son un hito clave en la historia reciente para el análisis de las relaciones entre Occidente y el Mundo Arabo-Islámico. El derrumbe de ... -
90Sr uptake in the freshwater liverwort Riccia fluitans L.
(2019-07-10)90Sr is a radioactive isotope of strontium produced by nuclear fission, with a half-life of 28.8 years. This artificial radioisotope is present in natural ecosystems as the results of radioactive fallout from nuclear weapons ... -
A "quick look" at ultrafast ablation using fs-resolved phase-change microscopy
(2016-09-27)A pump-probe phase-change microscope with fs temporal resolution has been used to understand the transformation induced in the sample surface as a consequence of laser-matter interaction. -
A bacterial acetyltransferase targets the protein kinase ZIP1, a positive regulator of plant immunity
(2016-06-27)Pseudomonas syringae is a model bacterial pathogen that penetrates the leaf to reach the plant apoplast, where it replicates causing disease. In order to do that, the pathogen must interfere and suppress a two-tiered plant ... -
A bayesian approach for one-way ANOVA under unequal variances
(2022)In this report a Bayesian solution to the problem of testing the equality of the means of k independent normal populations with unknown and arbitrary variances is provided. An important issue in the solution of this problem ... -
A Bayesian Solution to the Behrens-Fisher problem
(Springer, 2021-07)A simple solution to the Behrens–Fisher problem based on Bayes factors is presented, and its relation with the Behrens–Fisher distribution is explored. The construction of the Bayes factor is based on a simple hierarchical ... -
A bilevel framework for decision-making under uncertainty with contextual information
(Elsevier, 2021-11-22)In this paper, we propose a novel approach for data-driven decision-making under uncertainty in the presence of contextual information. Given a finite collection of observations of the uncertain parameters and potential ... -
A bottom-up robot architecture based on learnt behaviors driven design
(2015-06-17)In reactive layers of robotic architectures, behaviors should learn their operation from experience, following the trends of modern intelligence theories. A Case Based Reasoning (CBR) reactive layer could allow to achieve ... -
A Brain–Computer Interface Speller with a Reduced Matrix: A Case Study in a Patient with Amyotrophic Lateral Sclerosis
(2014-06-03)Visual P300-based Brain–Computer Interface (BCI) paradigms for spelling are aimed at offering a non-muscular communication channel for those people with severe motor impairment, such as locked-in patients. To be as effective ... -
A Broadband Cavity-Backed Slot for Series-Fed Arrays
(UMA Editorial, 2022-01-26)A pesar de que el diseño de antenas en el contexto de los sistemas de comunicaciones es uno de los desafíos más clásicos en la ingeniería de telecomunicación, las antenas para nuevas aplicaciones y servicios de reciente ... -
A broadband polarization splitter directional coupler based on tilted subwavelengh grating metamaterials
(2020-12-03)Tilted subwavelength gratings (SWG) allows anisotropy tailorable metamaterials with applications in polarization management. Based on this concept, here we experimentally demonstrate a broadband directional-couplerbased ... -

(2014-06-27)A central role for bifunctional aspartate/prephenate aminotransferase in the biosynthesis of amino acids in plant plastids. Fernando de la Torre, Jorge El-Azaz, Concepción Ávila, Francisco M. Cánovas Departamento de ... -
A characterisation of reliability tools for Software Defined Networks
(2017)Software Defined Network (SDN) is a new paradigm in networking that introduces great flexibility, allowing the dynamic configuration of parts of the network through centralised programming. SDN has been successfully applied ... -
A chemical biology approach to control endocannabinoid biosynthesis
(2015-04-15)Endocannabinoids play an essential role in human health and disease, regulating processes such as immunomodulation, energy balance and neurotransmission. Diacylglycerollipase-α (DAGL-α) is responsible for the production ... -
A Class of Well-Balanced Algorithms for Relativistic Fluids on a Schwarzschild Background
(SPRINGER, 2021-08-16)For the evolution of a compressible fluid in spherical symmetry on a Schwarzschild curved background, we design a class of well-balanced numerical algorithms up to third-order accuracy. We treat both the relativistic ... -
